15 Claims.

This invention relates to an improved fleshing machine.

One of the objects of the invention is to provide an improved flashingmachine.

Another object of the invention is to provide automatic means forremoving recoverable fats from skins and skin scraps.

Other objects of the invention will be apparent from the description andclaims which follow.

The device of the present invention comprises in combination a conveyingmeans and a fleshing means mounted relative to the conveying means.

The device requires only that the fat bearing skins be placed fat sideup upon the conveying surface whence they are carried relative tothefleshing means and the recoverable fat is removed. The device isapplicable within reason to skins of varying sizes and thicknesses. Itis easily operated and does not require highly skilled labor.

Reference is had to the drawings in which like characters of referenceare used to designate similar elements.

Figure 1 is a plan view of the device, the guard and means for drivingthe fleshing wheels being omitted.

Figure 2 is a side sectional view taken substantially on line 2-2 ofFigure 1.

Figure 3 is an enlarged side sectional view taken substantially on line37- 3 of Figure 2.

The device comprises broadly a means including endless conveyor Iadapted to carry continuously the skins 2 with their fat sides uprelative to fleshing rollers 3 and 4 of abrasive or other suitablematerial, the skins 2 being firmly held at their point of contact withrollers 3 and 4 by studs 5 cooperative with presser fingers 6 and I.

Endless conveyor I comprises a plurality of spaced transverse bars 8suitably mounted upon chains 9 which in turn are carried upon idlersprocket I0 and driven sprocket II.

Sprockets I0 and II respectively are pinioned y to shafts I2 and I3,journaled within suitable bearings I4. Bearings I4 are rigidly securedto framework I5 supported upon standards IS. The shaft I3 is driven bypower transmitted from motor I'I through the medium of gear box I8,chain r I3 and sprockets 20 and 2|,

* As viewed in Figure 3, the upper and lower flights of conveyor I areshown slidably supported upon angles 22 suitably secured to standardsIS.

The skins 2, before carriage to fleshing rollers 3 and 4, are firmlypressed into holding relationship with studs} by presser rollers 23crranged in series in longitudinal end to end relationship transverselyof conveyor I. Rollers 23 are supported as a unit by bracket 24 rigidlysecured as by bolts 25 and angles 26 to framework I5, and each of themis independently spring tensioned toward conveyor I through the mediumof a yoke 21, shaft 28 and spring 29 adjustably secured within asuitable opening provided in bracket 24 by threaded stud 33. The spring29 of each of the rollers 23 is compressibly secured between the yoke 21and slidable collar 3|. The shaft 28 is slidably mounted through stud 30and is limited in its downward movement by pin 32. The surfaces ofrollers 23 are longitudinally ribbed as at 33 to prevent slippage of thefat surfaces of the skins thereagainst. The provision of a series ofindependently movable presser rollers is found to uniformly press theskins regardless of differences of thickness of the skins carriedsimultaneously therebeneath.

The fleshing rollers 3 and 4, respectively, are pinioned or otherwiserigidly secured in longitudinal spaced relationship to shafts 34 and 35journaled within suitable bearings provided within risers 36 and 31.Risers 36 and 3'! are rigidly secured to framework I5.

It will be noted that the fleshing wheels 4 are aligned immediately tothe rear of fleshing wheels 3 and relative to the spaces 38 intermediatethe fleshing wheels 3 so that in combination the fleshing wheels 3 and 4present a continuous fleshing surface. It will be noted also that thespaces intermediate the fleshing wheels 3 and 4 allow for mountingpresser fingers 6 and I for pressing the skins firmly into holdingrelationship with studs 5 immediately at the point of contact of theskins with the fleshing wheels 3 and 4.

The presser fingers 6 and I are made of relatively firm but yieldablematerial and are rigidly secured by cross members 39, in pressibleengagement with the ends of studs 5. Cross mem bers 39 are pinionedwithin keepers 40 which in turnare rigidly secured to framework I3.

The shafts 34 and 35 are shown separately driven by power transmittedfrom a motor 4I through the medium of a belt 42 and pulleys 43 and 44.The motors II are mounted upon bracket 45 rigidly secured as by bolts 43to framework I5.

Header line 41 leads from a source of hot water supply not shown andprovides a branch line 48 for wetting each of the wheels 3 and 4 duringoperation thereof. The excess water passing from-the wheels 3 and 4 alsoserves to carry the recovered fat through the spaces provided betweenconveyor bars 8 and into tank 49 provided beneath conveyor I. Therecovered fat in tank 49 is carried by sloped bottom 50 through drainopening 5! to a catch basin not shown. As shown in Figure 2 a guardplate 52 may be mounted in any suitable manner above the wheels 3 and 4for the protection of the operator.

In operation the skins 2 are placed at random with their fat sides upupon conveyor I. The skins placed on conveyor l are pressed firmly intoholding relationship with studs 5 by presser rollers 23 and thereafterthe skins are carried beneath the rotating fieshing rollers 3 and 4whence the recoverable fat is removed therefrom. The skins immediatelyat their point of contact with rollers 3 and 4 are held firmly by thefingers 6 and 1 against the studs 5.
